SPECIFICATION forming part of Letters Patent No. 474,741, dated May 10,1892.

Application filed July 8, 1891- Serial No. 398,824. (No model.)

To all whom it may concern:

Be it known that I, LEWIS O. I-IURD, of Durango, in the county of LaPlata and State of Colorado, have invented a new and Improved \Vrench,of which the following is a specification, reference being had to theannexed drawings, forming a part thereof, in which- Figure 1 is aperspective view of my improved wrench. Fig. 2 is a front elevation, andFig. 3 is a side elevation.

Similar letters of reference indicate corresponding parts in all theviews.

The object of myinvention is to provide a simple, inexpensive, andefficient Wrench for turning and holding round or polygonal rods, nuts,and gas-burners; also, for the use of bicyclists for turning the spokesof bicycle-wheels.

My invention consists in a bar forked at one end and provided withserrations on the inner surface of one of the arms of the fork, beveledand serrated at the opposite end and furnished with a pivoted serratedjaw, designed to act, in conjunction with the serrated end of the bar,as an adjustable wrench for turning or holding round or polygonalobjects.

It also consists in a screw-driver blade attached to or formed upon thepivoted jaw, all as will be hereinafter more fully described.

The barA, formed of steel or other suitable material, is provided at oneend with a fork B, having the arms a a. The inner surface of the arm a.is serrated or provided with ratchet-teeth c for engagement with theobject to be turned or held. The opposite end 5 d of the barAis beveledand serrated, and to the bar is pivoted a jaw O, having arms 6 e,extending downwardly on opposite sides of the bar and connected with thebar by the pivotal rivetf. The inner surface of the jaw C is beveled toconform to the angle of the end (1 and corrugated, as shown. The outereX- tremity of the jaw O is provided with ashort screw-driver bladeg,which extends outwardly parallel with the line of the bar A when thejaw O is closed.

The angle of the fork Bis such as to cause any object received by it towedge into the jaw as the teeth a are brought into engagement with thesurface of the fork and the wrench is turned in the direction requiredto secure a firm grip on the bar.

lVhen the opposite end of the wrench is used, the object to be turned orheld is received between the jaw O and the serrated end (Z of the bar A,so that by turning the wrench the jaw C is brought into close engagementwith the bar by swinging over the end of the bar.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- As a new article of manufacture, a wrench consistingof the bar A, having the beveled and serrated end (I and the forked endB, the inner surface of one member of which is serrated, and the beveledand serrated jaw 0, having the arms 6 6, extending down on oppositesides of the barAand pivoted thereto, and provided with the screw-driverblade g, projecting from its upper surface, as set forth.
